4. - 1. Foreign judgments are authenticated in various ways; 1. By an exemplification, certified under the great seal of the state or country where it was rendered. 2. By a copy proved to be a true copy. 3. By the certificate of an officer authorized by law, which certificate must, itself, be properly authenticated. 2 Cranch, 238; 2 Caines' R. 155; 5 Cranch, 335; 7 Johns. R. 514 Mass. R. 273 2 Munf. R. 43 4 Camp. R. 28 2 Russ. on Cr. 723. There is a difference between the judgments of courts of common law jurisdiction and courts of admiralty, as to the mode of proof of judgments rendered by them. Courts of admiralty are under the law of nations; certificates of such judgments with their seals affixed, will therefore be admitted in evidence without further proof. 5 Cranch, 335; 3 Conn. R. 171.
5. - 2. A judgment rendered in a foreign country by a court de jure, or even a court defacto, 4 Binn. 371, in a matter within its jurisdiction, when the parties litigant had been notified and have had an opportunity of being heard, either establishing a demand, against the defendant or discharging him from it, is of binding force. 1 Dall. R. 191; 9 Serg. & Rawle, 260; 10 Serg. & Rawle, 240; 1 Pet. C. C. R. 155; 1 Spears, Eq. Cas. 229; 7 Branch, 481. As to the plea of the act of limitation to a suit on a foreign judgment, see Bac.
